qBittorrent kills connection

Post by PoonT »

Hey, I've recently begun experiencing a big issue on qBittorrent 4.3.3 windows installer version.
What happens is that every 1-10 minutes my network completely drops on my PC, but only on my PC. This lasts for about 5-10 seconds each time. Other devices on network continue to work. It's not router's fault because connections to other devices from my PC bypassing router also fail (directly through unmanaged switch).
I uploaded a screenshot of pinging devices (top left: google, top right: router, bottom left: device on LAN cable connected, bottom right: device on LAN wifi connected). As you can see the whole network stack dies. This usually happens when seeding. Upload speed affects how often this occurs it seems. At about 7MB/s it happens in 1-10 minute intervals generally. At lower speeds it's less frequent or pretty much gone under 500kB/s. I don't know if there's any correlation with connected peers but right now it happens at around 40 connected peers and when it starts happening connected peers start increasing for some reason even tho connection is dead (goes to about 50-60 before dropping back down to 10 in statistics [ctrl+i] and then recovering). Currently have 36 active torrents, only 2-3 with active peers.

Also I limit my upload in qbt to about 70% (7.5MB/s) of all possible upload (unlimiting this has no effect). When qbt is closed this never happens. Also didn't happen in utorrent.
I can download at 100MB/s with many peer connections and this won't happen.

Also another interesting bit:

Code: Select all

Why did it ping my ip (.169) there when I am pinging .21.

My PC specs:
128gb ram
5950x ryzen
Windows 10

What seems to have fixed it is disabling Intel NIC and Wifi in bios. Only left the Realtek one alive.
